Incremental path
Technology levels of the incremental path | |
---|---|
Level 0 | side products |
Level I | side products |
Level II | side products |
Level III | pre-products products maybe |
The incremental path is a second pathway to advanced APM systems beside the direct path.
In Appendix II of the book "Radical Abundance" [1] it is proposed to go through several levels of APM technology to reach advanced (atomic resolution & diamondoid) APM. These layers will serve as a rough guideline for the structuring of this Wiki.
In "Nanosystems" [2] technology stages are mentioned beginning with section 16.5.2. (written before the emergence of structural DNA nanotechnology)
The recently developed self assembling structural DNA nanotechnology and similar reliably designable structures might be a good starting point from technology level 0. By introducing robotic (more precisely stereotactic) control one could reach something like a "block resolution robotic technology" technology level I from there in a first step. In a second step one could change to e.g. Pyrite or Silica technology level II as building material to increase structural stiffness, reduce vibration amplitudes and get thus more placing accuracy. And finally in a third step one could switch from fluid phase to vacuum so that carbon and silicon can be assembled technology level III.
This very crude temporal outline is by no means the only possible way to go. There may be shortcuts or other paths.
Note: The definition of atomic precision does not imply single-atomic manipulation. The derived term "APM" also tells nothing about product size. It is thus suitable for todays self assembly and all technology levels beyond 0.
Advanced levels of APM though are capable of macromanufacturing of diamondoid structures with atomic resolution.
Since a nanofactory at the endpoint of an incremental path will inherit the capability of handling at least the materials of one generation before it may be better to call the products gemoid instead of diamondoid this terminology would make it more clear that gemstone like bio-minerals like quartz are included.
Paths that are treated separately because its harder to find a cncrete goal for them
Note that the behavior of mobile electrons at the nanoscale is not as easily predictable as the behavior of mechanics at the same scale thus there's less exploratory engineering for nanoelectronics than nanomechanics. See:
- non mechanical technology path (including nanoelectronics)
- brownian technology path. (including things like synthetic biology)
